Car shaking over 70mph

[Jonny T]

My mx3's vibrating violently at speeds over 70mph,can feel it mostly through the steering wheel,the wheels are balanced and the tracking is perfect,also makes a loud creaking noise when i turn the steering wheel? Has any 1 had any similar problems? thanx

probably allignment.. but who knows, could be wheel bearings or balancing. LOL get it looked at by a shop

[GoT_DaT_Mx3_Se]

yeah, ive got the same problem. i had my wheels balanced but it didnt seem to help. the same thing happens on the miata too. maybe its a mazda thing.

balljoint?

[johnnyb]

what kind of shape are your tires in? Uneven wear on your tires will balance fine but when you drive a certain speed will cause the car to bounce. I had the same problem with my work van, had the tires replaced and the problem went away

i am thinking wheel bearings

[johnnyb]

I would have said wheel bearings but it wouldnt shake violently all of a sudden, he'd have a warning first

[Jonny T]

The allignment has just been done and the wheels and tyres are brand new plus iv just replaced a ball joint,im thinkin maybe its a wheel bearing although its not really wining plus theres a nasty creaking noise at slow speeds,thinkin maybe its the steering rack,problem is mx3's are pretty rare in the uk so garages dont have a lot of experience with them and mazda dealers cost a bomb,it is a beautiful car tho and maybe worth spending the exra money

I shudda mentioned too that the cars done 150000 miles,its pissin me off now,have 2 back out of races when i hit 80mph cos it feels like im doin warp 10

Let me get this right. It makes a loud creaking noise when you turn the wheel and theres a nasty creaking noise at slow speeds.

And you're racing up to 80 mph.

So far so good, but where you racing?

hmm my car starts to shake at around 90 mph , and my problem is the rear strut..speciall when it rains (water goes inside) Now um from what I have experienced in other cars (older) when the wheel "Cracks" while turning and it shakes at high speeds..its the ball join and or bearing. I know because my 92 ford escort gt had the sam thing....Just went and got a bearing and joint job (30 dlls across the boder) and it fixed it right up. Oh and um..dont drive at 80 mph in this conition.I had a maxima tha had a bearing seize at 50 mph and it was NOT pretty at all..its like slamming on the brake but for only that tire..acr swirves to the right and you end up in the median or even worse...rolled over.

Uhh... then dont go 90!

Ok, I found the answer to my problem And i know it IS this.. I went to go buy new rear tires and what do ya know....my rear aligment is off, so thats why it shakes I was about to die i guess...since the rear tire was all rimmed from the edge trough the inside. so yeah tomorrow first thing in the morning I go for my 4 wheel aligment and my other rear tire (they only had one available for some odd reason) So yea dude..i think its an alignment issue..most likely.

I get a slight vibe at around 70mph, but as soon as I get past it it goes smooth as glass right through 100mph. probably a slight balancing issue, but meh, not much.
